Anyone who has a sizable mp3 collection is going to run into the problem of having duplicate songs in their albums. Over the course of the last few weeks I've asked many of my friends if they've run into the same issues and every single one of them told me that iTunes duplicates songs in their albums - and that they have to manually go in and make it right again. If you do a google search you will see that many people have this issue. And you will also see many mac fanboys trying to tell them that it's not an issue...or they'll advise an annoying workaround that might as well be manual because you still basically have to go in and fix things album by album.

iTunes should know the sequence and tracks in any particular album based on the ID3 tags and should keep things organized that way. I don't see how you can even make the argument that the way iTunes does it now is best.
